Method of screening crude oil for low molecular weight naphthenic acids |
摘要 |
A method for the quantitation of the naphthenic acid content of molecular weight less than 600 daltons in a hydrocarbon composition, comprising (i) separating naphthenic acids from the hydrocarbon composition and applying them to a macroreticular ion-exchange resin. The resin is washed and the naphthenic acid-metal ion complexes are eluted from the resin. The number of naphthenic acid-metal ion complexes present in the eluate from the resin are quantitated. |
